The camera takes blurry pictures

You have a couple of options here. The first thing I would suggest is to make and sure that the lens itself doesn't have any residue that could be affecting the camera.

Next, try turning the device off and on and see if it is fixed, it's possible that the problem was just a glitch.

If you are still having problems, try downloading a picture-taking app. There are tons of options and this could be a solution if the problem is in fact a software issue. There are also apps devoted to sharpening blurry images so check those out too.

If it still isn't resolved, it's probably a hardware issue, in that case look at the guide that covers camera replacement.
